Another mirror idea...
Zeta pro guards with crg style round mirrors mounted forward of the bar end on the hand guard itself. Offers a better view imo. One ride with it today and it works really well.
Will those mirrors work on the stock hand guards?
I’m sure you could mount them as others have mounted the CRG Arrows which mount the same but are different shape.
Another option is the CNC Racing Rocket mirrors which are fantastic & mount very cleanly with the included M6 bolt & you retain the stock brass insert in the handlebar. It sits up against the handguard very nicely which is why I chose them & when folded in they are narrower than stock which is important to me as I live in CA where lane splitting is legal.
